How a VC Can Affect Your Heart

A lot of people experience occasional PVCs and have no issues. If they occur regularly, PVCs can weaken your heart muscle and increase the risk of heart failure.

A bundle of fibers in the upper right part of your heart (the sinoatrial node, also known as SA) usually controls the heart's rhythm. Electrical signals travel to ventricles, or lower chambers of the heart.

Causes

PVCs occur when the electrical impulse that usually initiates your heartbeat in a region known as the sinus node (also called the sinoatrial or SA node) isn't. The impulse actually starts in the ventricles, causing a mistimed heartbeat. These extra beats are known as ventricular tachycardia, and ventricular fibrillation. It may feel like the heart beats faster or feels like it is fluttering. They may occur infrequently and not cause any symptoms, but they may occur frequently enough to impact your quality of life. Your doctor might prescribe medication in the event that they are frequent or cause dizziness, weakness or fatigue.

For windows doctor , PVCs are harmless and do not increase the risk of developing heart disease or other health issues. A lot of PVCs, however, can weaken your heart muscle over time. This is particularly true if they are caused by a heart disease such as dilated cardiomyopathy arrhythmogenic right ventricular cardiomyopathy, which may lead to symptomatic heart failure.

The signs of PVCs include a feeling that your heart skips a beat or flutters, and you may feel breathless. The fluttering can be more noticeable when you exercise, or consume certain drinks or foods. PVCs are more prevalent for those who suffer from chronic stress or anxiety. Certain drugs, like digoxin, amiodarone, and cocaine, can also increase their risk.

If you experience occasional PVCs your doctor may recommend lifestyle changes and medications. If you experience frequent PVCs, your doctor may suggest that you stay away from certain foods and drinks such as alcohol and caffeine. You can also reduce your stress and make sure you get enough sleep and exercise.

If you have many PVCs, your doctor may suggest a medical procedure known as radiofrequency catheter ablation. This procedure eliminates the cells that are responsible for them. Electrophysiologists are the ones who execute this procedure. It is usually effective in treating PVCs and reducing symptoms, but it doesn't stop them from occurring in the future. In some cases it can increase the risk of developing atrial fibrillation (AFib), an illness that can result in stroke. It's not common, but it can be life-threatening.

Symptoms

Premature ventricular contractures, or PVCs can cause your heart to skip or flutter. These extra heartbeats are usually harmless, however, you should consult your physician when you experience frequent episodes or other symptoms such as dizziness or weakness.

The normal electrical signals start in the sinoatrial region, which is in the upper right-hand part of the heart. They then move to the lower chambers, or ventricles, where blood pumps are located. The ventricles then contract to propel blood into the lungs, and return to the heart to start the next cycle of pumping. But a PVC begins in a different place and is located in the bundle of fibers known as the Purkinje fibers, located in the bottom left portion of the heart.

When PVCs occur, they cause the heart beat or feel like it skipped a beat. If you have only a few episodes, and no other symptoms are present your cardiologist may not treat you. But if you have a number of PVCs and you have other symptoms, your doctor might recommend an electrocardiogram, or ECG to determine your heartbeat over the course of 24 hours. They may also suggest wearing a Holter Monitor, which records the heart's rhythm and count the number of PVCs.

If you've suffered a heart attack in the past or have cardiomyopathy -- a condition that alters the way the heart pumps blood- must be aware of their PVCs and speak with a cardiologist about changes to their lifestyle. These include avoiding caffeine, alcohol and smoking, managing anxiety and stress, and getting enough rest. A cardiologist might prescribe medications to slow the heartbeat such as beta blockers.

Even if you don't experience any other indications however, you should have PVCs checked by an cardiologist if they occur often. These irregular heartbeats could be a sign of a problem with the structure of your lungs or heart, and if they happen often enough, can weaken your heart muscle. Most people with PVCs don't experience any issues. They want to know if the fluttering heartbeats or skipping heartbeats is normal.





Diagnosis

PVCs can feel like fluttering or skipped heartbeats, especially when they are frequent or intense. People who experience them often may feel faint. Exercise can cause PVCs, but a lot of athletes who suffer from these symptoms do not have heart or health issues. PVCs can show up in tests like an electrocardiogram, or Holter monitor. They have sensors that record electrical impulses from your heart. A cardiologist could also employ an ultrasound echocardiogram to examine the heart.

A doctor will usually be able to determine whether a patient has PVCs by looking at them and taking a medical history. However, sometimes they will only be able to detect them when they examine the patient for other reasons, such as following an accident or surgery. Ambulatory ECG monitors can detect PVCs and other arrhythmias. They can be used to detect heart disease when there is a concern.

If your cardiologist determines that your heart's structure is normal, reassurance is the only treatment needed. However, if your symptoms are troubling or make you feel anxious, staying away from caffeine, alcohol and over-the-counter decongestants and reducing stress can aid. Engaging in regular exercise, keeping at a healthy weight and drinking enough water can help reduce the frequency of PVCs. If you are experiencing symptoms that are persistent or severe, talk to your doctor about medications that could be able to control them.

Treatment

If PVCs do not cause any symptoms or happen rarely generally, they don't require treatment. If you experience them frequently or frequently, your doctor may wish to examine for any other heart problems and suggest lifestyle changes or medication. You may also undergo a procedure (called radiofrequency cathode ablation) to get rid of them.

If you suffer from PVCs The electrical signal that causes your heartbeat starts somewhere outside of the sinoatrial node (SA node) in the top right corner of your heart. This could cause your heart to feel as if it skips beats or has extra beats. It's not clear what causes these, but they're more common in people who have other heart problems. PVCs are more likely to occur as you age, and might occur more frequently during exercise.

If a patient experiences frequent and painful PVCs doctors should perform an ECG and an echocardiogram to determine if there is a structural heart problem. The doctor will also conduct an exercise stress test to determine if the additional heartbeats are caused by physical activity. A heart catheterization, cardiac MRI or nuclear perfusion study could be performed to find other reasons for the extra beats.

The majority of people with PVCs don't experience any complications and can lead an ordinary life. They could increase the risk of dangerous heart rhythm disorders particularly if they happen in certain patterns. In some cases, this means that the heart muscle gets weaker and it is more difficult to pump blood throughout your body.

A regular, healthy diet and a lot of exercise can help reduce your chances of developing PVCs. Avoid foods high in sodium and fat, and limit your intake of caffeine and tobacco. It is also important to get enough sleep and reduce stress. Certain medications can increase the risk of getting PVCs. So if you take one of these medicines it is important to follow your doctor's instructions about a healthy diet, exercise and taking your medication.

Studies of patients suffering from an excessive amount of PVCs (that's more than 20 percent of their total heart beats) found that they had a higher risk of arrhythmia-induced cardiomyopathy. This could lead to a need for a heart transplant in certain individuals.
